Abstract

A compressor piston that smoothly slides in a cylinder bore and a coating method for manufacturing such pistons. Coating material (C) is applied to a piston (22) to form a coating layer (35). The principal components of the material (C) include fluororesin (36) and a binder (37). The coating layer (35) is not ground. Therefore, fluororesin (36), which migrates to the surface of the coating layer (35), is not removed by grinding, which permits the piston (22) to resist friction.
